iSQI CTFL_Syll_4.0 Exam With Confidence Using Practice Dumps

In the given decision table, Column 7 represents the following conditions and actions:

The patient is over 18 years old: True

The patient is allergic to Penicillin: True

The patient is taking anticoagulant therapy: True

When analyzing this column:

If the patient is over 18 years old, allergic to Penicillin, and taking anticoagulant therapy, the decision table suggests consultation with a hematologist and prescribing half of the full recommended dosage for 10 days.

This column does not represent an impossible situation based on the conditions provided. However, upon deeper inspection and understanding of medical practices, it can be argued that such a specificcombination of conditions could be highly unlikely, making it appear unnecessary or an edge case that might be considered for deletion.

Given the constraints of the conditions and the requirements of the decision table, the provided answer needs to be verified against real-world medical guidelines to confirm if this scenario is indeed impossible or just

In branch testing, a conditional branch represents a decision point in the software program where the flow of execution can take different paths based on specific conditions. For example, this could be an "if-else" statement, a "switch-case" statement, or loops where different execution paths are taken depending on the evaluated condition. This type of testing ensures that all possible paths and conditions are executed at least once, which helps in identifying any potential defects in different branches of the code​​.

Comprehensive and Detailed Explanation From Exact Extract:

This question applies theState Transition Testingtechnique.

Let’s evaluateOption Dstep-by-step:

NORMAL MODE → DEGRADED MODE:✅Valid on“FAILURE DETECTED”

DEGRADED MODE → NORMAL MODE:✅Valid on“ALL FAILURES CLEARED”

NORMAL MODE → DIAGNOSTIC MODE:✅Valid on“SELF DIAGNOSTIC INITIATED”

DIAGNOSTIC MODE → DEGRADED MODE:❌Invalid– there isno defined transitionfrom DIAGNOSTIC MODE directly to DEGRADED MODE.

According to the state diagram, DEGRADED MODE can only be entered:

From NORMAL MODE (on FAILURE DETECTED), or

Not from DIAGNOSTIC MODE at all.

This violates the rule:

“State transition testing uses a model where test cases are designed to execute valid and invalid transitions.”

(ISTQB CTFL Syllabus v4.0, Section 4.2.4 – State Transition Testing, Page 40)

Thus, OptionDcontains aninvalid transition, making it the correct answer.
